No. 752,128 Claims priority, application Germany Aug. 2, 1957 2 Claims. (Cl. 13837) This invention relates to apparatus, such as containers, shaft driers and the like, for the storage or treatment of coke or other materials which are in the form of coarse pieces.

It has been proposed to protect the inner Walls of shaft driers from wear by providing them with a protective coating, for example of fused basalt. Such coatings, however, are very expensive. Furthermore, the drying of many materials takes place at such high temperatures that a fused basalt protector can not be used.

We have found that an excellent protection of the Walls of receptacles, such as containers for the storage of coke or other coarse-pieced materials, or apparatus, such as shaft driers, for the treatment of such materials, against Wear by the abrasive action of the coarse-pieced material can be achieved by providing the inner walls of the receptacle with bearer members arranged one above another in spaced relationship, and providing rings which lie on said bearer members and which are concentric with the wall. The bearer members projecting from the wall may be rings or may be individual brackets spaced from each other and situated at single points in a cross-sectional plane of the receptacle, and these bearer members may be firmly fixed to the wall, for example by Welding. 'It is advantageous to use rings as the bearer members because these act at the same time to stiffen the wall of the receptacle. The rings which lie on the bearer members may consist for example of fiat iron, profiled cast iron or ceramic material. It is preferable to choose the width of these rings greater than the width of the bearer members so that the edge of each ring facing the interior of the receptacle projects over the corresponding edge of the bearer member.

In order to facilitate introduction of the rings into the receptacle, they are introduced subdivided into segments and laid on the bearer member as such or joined together in situ in known manner.

The exchangeable rings provided on the Wall of the receptacle substantially prevent the layer of material which is migrating downwardly through the receptacle from exer-ting an abrasive action on the wall, because beneath the rings the lateral pressure of the layer of material on the wall is abolished or considerably reduced and after a short operational period layers are built up on the rings and along the wall which consist substantially of finer parts of the material which do not participate in the sliding movement of the material through the receptacle.

Furthermore the layers of material built up along the wall of the receptacle effect a heat insulation.

Wear by the abrasive action of the material is limited according to this invention to the rings provided in the receptacle. Since these rings are readily replaceable, the renewal of the same involves only a slight cost as compared with a renewal of the wall of the receptacle.

The accompanying drawings illustrate diagrammatically an apparatus according to this invention, FIGURE 1 being a sectional elevation, FIGURE 2 a plan of one of the rings, and FIGURE 3 an enlarged detail.

Referring to the drawings, 1 is a shift drier having heating gas supply shafts in 2, bearer members 3 and fiat rings 4 laid thereon. FIGURE 2 shows in plan a single subdivided flat iron ring. FIGURE 3 shows on a larger scale a bearer member 3 with its superposed ring 4 and the layer of finer material which builds up along the wall of the shaft drier.

We claim:

1. A cylindrical receptacle through which coarse pieces of coke or the like are passed which comprises bearer members fixedly attached to and projecting from the inner wall of said cylindrical receptacle, said bearer members being arranged at points in several spaced cross-sectional planes of said receptacle; ring members positioned on said bearer members, said ring members being concentric to and in contact with said inner wall of the receptacle and extending inwardly substantially at a right angle to said wall; said cylindrical receptacle including ingress means for said coarse pieces at its top and means for withdrawing said coarse pieces at the bottom of the receptacle.

2. A cylindrical receptacle through which coarse pieces of coke or the like are passed which comprises ring members attached to and projecting from the inner wall of said cylindrical receptacle, said ring members being arranged in several spaced cross-sectional planes of said receptacle, said ring members being concentric to and in contact with said inner wall and extending inwardly substantially at a right angle to said wall; said cylindrical receptacle including ingress means for said coarse pieces at its top and means for withdrawing said coarse pieces at the bottom of said receptacle.
